Question about JVC LT-42E478 42 in. LCD Television
Tv turns on all all inputs are fine but color on all channels and inputs are distorted as well as the clarity of the picture. I believe colorwheel is out.. Can I fix it or repair it myself?
This set indeed will not have a colour wheel this immediately tells me you are not electronically trained , my advice seek a pro to look at your set . There could be a number of faults such as 1/ faulty Lcd Backlight, 2/ faulty inversion circuit ( the back light is similar to a neon and requires a starter and high power inverters )
3/ Faulty Tcon board
4/ it could also be the printed copper ribbons that interconnect the boards in the set these get hard brittle and crack over time .
5/ you could actually have a faulty lcd screen .
No to save you money and further damage to set seek an engineer , sorry to sound condescending but I don't think DIY is going to solve this problem.

LCD tv don't have colors wheel,only DLP tv have colors wheel.Distorted picture have only two symtoms.The Tuner signal board is dead,replaced that.Same problems than Ur LCD screen is dead,not worth repairing if the LCD screen is the problem.Because the LCD can only buy at the tv dealer they sell them very expensive cost about the same as a new tv.Tries Shopjimmy.com,Ebay.com for the Tuner board.

Based on the Model# provided, your TV does not have a color wheel. Could be one of the PCBs is bad, or even the panel. Have a TV technician look at it.
